The Greeks related the movements of the stars to each other and devised a cosmos of spherical shape, whose center occupied an igneous body and around it revolved the Earth, the Moon, the Sun and the five known planets; the sphere ended in the sky of the fixed spheres: To complete the number of ten, which they considered sacred, they imagined a tenth body, the Anti-Earth.

In Greece, what we now know as Western astronomy began to develop. In the early days of Greek history, the earth was considered to be a disk in the center of which was Olympus and around it the Okeanos, the universal sea. The main purpose of the astronomical observations was to serve as a guide for the farmers, so they worked hard to design a calendar that would be useful for these activities.
